DOT11_DATA_RATE_MAPPING_ENTRY (Compact 2013)

3/26/2014

This structure defines a data rate supported by a PHY on the 802.11 station for transmit and receive operations.

Syntax

typedef struct DOT11_DATA_RATE_MAPPING_ENTRY {
  UCHAR  ucDataRateIndex;
  UCHAR  ucDataRateFlag;
  USHORT  usDataRateValue;
} DOT11_DATA_RATE_MAPPING_ENTRY, *PDOT11_DATA_RATE_MAPPING_ENTRY;

Members

• ucDataRateIndex
  The index value for the data rate contained in the usDataRateValue member. The value of the ucDataRateIndex member must be unique for each entry in the DataRateMappingEntries array.

  This value is a bitmask as defined in the following table:

  Bits	Description
  0-6	The data rate index that contains a value from 2 through 127
  7	This bit is not used and must be set to zero

• ucDataRateFLag
  The attributes of the data rate entry.

  This value is a bitmask as defined in the following table:

  Bits	Name	Description
  0	DOT11_DATA_RATE_NON_STANDARD	If set, the entry is not a standard data rate defined in IEEE 802.11 standards
  1-7	-	These bits are not used and must be set to zero

• usDataRateValue
  The data rate that is defined in units of 500 kilobits per second (Kbps), with a value from 0x0002 to 0xFFFF

Remarks

For the IEEE 802.11 standard data rates, the miniport driver must set the ucDataRateIndex and usDataRateValue members to the same value.

The following table shows the IEEE 802.11 standard data rates, in units of megabits per second (Mbps), and the related values for the ucDataRateIndex and usDataRateValue members:

IEEE 802.11 Standard Rate	ucDataRateIndex	usDataRateValue
1 Mbps	0x02	0x02
2 Mbps	0x04	0x04
3 Mbps	0x06	0x06
4.5 Mbps	0x09	0x09
5.5 Mbps	0x0B	0x0B
6 Mbps	0x0C	0x0C
9 Mbps	0x12	0x12
11 Mbps	0x16	0x16
12 Mbps	0x18	0x18
18 Mbps	0x24	0x24
22 Mbps	0x2C	0x2C
24 Mbps	0x30	0x30
27 Mbps	0x36	0x36
33 Mbps	0x42	0x42
36 Mbps	0x48	0x48
48 Mbps	0x60	0x60
54 Mbps	0x6C	0x6C
